Commentaries of the Four Authorized Vaisnava Sampradayas

Continuing Lord Krishna explains the result of raja guna or mode of passion
being prredominant at the time of death is that the jiva or embodied being
is born into families that are are involved in vigorous activity, Likewise
the result of tama guna or mode of ignorance being predominant at the
moment of death then the jiva is born in the wombs of irrational species as
animals.

Sri Vaisnava Sampradaya:

Ramanuja

Ramanuja's Commentary

Now Lord Krishna describes that when a jiva or embodied being dies while in
raja guna or the mode of passion one takes birth among those who perform
activities out of desire for rewards and having been born as such will
endeavour mightily to accomplish works that would be rewarded by immense
wealth and power even up unto the heavenly spheres. Similarly if one dies
while under the influnce of tama guna or the mode of ignorance then such
jivas will be born from the wombs of animals such as pigs and dogs where
one would be completely incapacitated to perform any activity that would
give any spiritual benefit.

Kumara Vaisnava Sampradaya:

Nimbaditya

Kesava Kasmiri's Commentary

Lord Krishna states that if death comes upon a jiva or embodied being while
predisposed to raja guna or the mode of passion then one takes birth next
from those who are obsessed to perform actions in anticipation of rewards .
Also a jiva dying while under the influence of tama guna or mode of
ignorance is forced to take birth as an animal in the next life.
